Title: Power supply control circuit
Inventor: YOSHIMURA KAZUO
IPC: H04B1/04
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To prevent breakdown when supplying power to an amplifier requiring positive and negative power supplies as a drive power supply such as MMIC. SOLUTION: When power is turned on, a positive power supply circuit 1 is turned on, a negative power supply circuit 2 starts operating at a first reference voltage or higher, and a negative voltage rises to a nearly constant voltage at a second reference voltage. A negative voltage detection circuit 4 detects the negative voltage until this point and outputs a negative voltage detection signal. Also, the negative voltage is directly applied to a negative voltage supply terminal 7b of an MMIC 7. When the positive voltage further rises to a third reference voltage, a positive voltage detection circuit 5 operates and outputs a positive voltage detection signal.  A judgment circuit 6 turns on a switch circuit 3 when both negative and positive voltages are inputted and applies a positive voltage to a positive voltage supply terminal 7a of the IC 7, thus preventing the positive voltage from being applied before supplying the negative voltage. When a power supply is interrupted, the positive voltage is turned off before the negative voltage stops.

Title: Stylus pen
Inventor: SOMEYA HISAO
IPC: G06F3/033
Filed: 1992-07-13
Abstract: PURPOSE:To prevent the damage of a pressure sensor beforehand when a shock is added to a pen point by transmitting the force added to the pen point to the pressure sensor via liquid material within a pressure chamber. CONSTITUTION:When a pen point 13 is brought into contact with an input/ output board, holding a pen holder 11, and is pressurized, a piston 14 pressurizes the liquid material within a pressure chamber 25 by the force in accordance with the pressure via a gum diaphragm 24. As a result, the pressure within the pressure chamber 25 rises, it is detected by a pressure sensor 20 and the output in accordance with the size of the pressure imparted to the pen point 13 is generated from an output terminal 28. Even if a shock is added to the pen point 13, pressure is added to the pressure sensor 20 via liquid material within the pressure chamber 25. As the force added to the pen point 13 is evenly added to the wall surface of the pressure chamber 25, little force is added to the pressure sensor. Therefore, the damage of the pressure sensor can be prevented.
